SDL Trados Studio 2021 Editor keyboard lag

When typing in the Editor View of SDL Trados Studio 2021, there is a noticeable lag or delay between the keystrokes and the characters appearing on the screen. This problem does not occur in any other application. My system has an AMD FX 6300 six-core x64-based 3.50 GHz processor, 16 GB RAM and 64-bit OS. Does anyone have suggestions for how to correct this problem?
